Pim van den Berg d00e948208 feat(itho-wpu): rm slave thread + pass result to I2CMaster via a queue + add retry mechanism

Remove the slave thread, set_callback already spawns a thread.

I2CSlave.callback() now puts the result (if valid) in a queue. This item
can be picked up by I2CMaster for further processing.

I2CMaster will wait 0.21s for a result in the queue. 0.21s, because I
always see a response in < 0.2s. If there is no result, it will send the
request again (max 20 retries). This is because I don't get reliable
responses (via pigpiod?). In an earlier commit I mentioned to configure
pigpiod with -s 2 (sample rate 2 microseconds).  This doesn't seem to be
true. For example -s 10 gives the same reliability (and less CPU usage
by pigpiod).
